They were joined by Simon Cowell's Groups Jack and Joel, Sean and Conor Price, The CutKelvins and Rak-Su and Louis Walsh's boys Leon Mallett, Lloyd Macey, Spencer Sutherland and Sam Black.

A series of live performances and brutal elimination rounds followed that only the strongest survived.

There was no bottom two sing-off with viewer votes alone deciding the winners and losers each weekend.

The first round saw two eliminations as Spencer Sutherland and Talia Dean went home after the first viewer votes. In Week 2, the Boys and Overs categories each again lost another act as Leon Mallett and Tracey Leanne Jefford were sent home.

In Week 3, the Girls and Groups lost their first acts as Alisah Bonaobra and duo Jack and Joel were voted off by the public. In Week 4, it was a quadruple elimination as Holly Tandy, Rai-Elle Williams, Sam Black and Sean and Conor Price were all voted off.

In the semi-finals, a trio went home with Matt Linnen, and The CutKevlins and Lloyd Macey all leaving.
